n8agrin / linear_scale.js

Created March 22, 2013 22:26

Simplified linear scale based on d3.

function uninterpolate (a, b, x) {

b = b - (a = +a) ? 1 / (b - a) : 0;

return (x - a) * b;

}

function interpolate (a, b, t) {

return (a + (b - a)) * t;

}

// Given a domain [0, 10], a range [0, 100], and a value (v),

This stacked bar chart is constructed from a CSV file storing the populations of different states by age group. The chart employs conventional margins and a number of D3 features:

d3.csv - load and parse data
d3.scale.ordinal - x-position encoding and color encoding
d3.scale.linear - y-position encoding
d3.format - SI prefix formatting (e.g., "10M" for 10,000,000)
d3.max - compute domains
d3.keys - compute column names
d3.svg.axis - display axes

This simple bar chart is constructed from a TSV file storing the frequency of letters in the English language. The chart employs conventional margins and a number of D3 features:

d3.tsv - load and parse data
d3.format - format percentages
d3.scale.ordinal - x-position encoding
d3.scale.linear - y-position encoding
d3.max - compute domains
d3.svg.axis - display axes

n8agrin / myclass.js

Created May 15, 2012 18:12

A simple, if old, class system for Javascript.

// The best javascript class system ever! This is old news to most, but

// more and more I find myself coming back to this. I don't have a vendetta

// against the `new` keyword. I just sometimes want encapsulation in a way

// that doesn't feel like a complete hack.

// Start with a closure

var vehicle = function() {

// Use Object.create

var vehicle = Object.create({});
